This module is useful when checking an entire network
|
|
of SMB hosts for the presence of a known file or directory.
|
|
An example would be to scan all systems for the presence of
|
|
antivirus or known malware outbreak. Typically you must set
|
|
RPATH, SMBUser, SMBDomain and SMBPass to operate correctly.
